Solution Overview

Smart Storage for Business & Industry

Yiwei's commercial and industrial energy storage solutions help factories, parks, and commercial buildings reduce electricity costs, manage demand charges, and ensure reliable backup power. Our liquid-cooled outdoor cabinets are engineered for high-cycle performance and long service life in demanding environments.

Our C&I systems combine lithium iron phosphate battery packs with high-efficiency PCS and an intelligent energy management system. The EMS automatically executes peak shaving, valley filling, and demand charge management strategies based on real-time load data and tariff structures.

From standalone storage to integrated PV+storage+EV charging systems, Yiwei delivers scalable configurations from 100 kWh to multi-MWh installations across manufacturing, logistics, retail, and public infrastructure sectors worldwide.

Key Benefits

Cut Costs. Ensure Reliability.

A complete C&I energy storage system that delivers measurable savings and operational resilience for businesses.

01

Peak Shaving & Valley Filling

Charge during low-tariff off-peak hours and discharge during high-tariff peak periods, directly reducing energy costs and flattening your load profile.

02

Demand Charge Management

Automatically discharge storage when demand approaches your contracted capacity threshold, avoiding costly demand charge spikes and penalties.

03

Backup Power & Resilience

When the grid fails, the system seamlessly switches to backup mode, keeping critical production lines, data centers, and safety systems online without interruption.

04

PV + Storage + EV Integration

Integrate on-site solar generation and EV charging infrastructure with storage to maximize self-consumption, reduce grid dependency, and support green operations.

System Design

Built for High-Cycle Duty

Every C&I storage system is built around liquid-cooled battery cabinets, modular PCS, and a unified EMS platform. Modular design allows capacity expansion from 100 kWh to multi-MWh without system redesign.

  • Liquid-cooled LFP battery cabinets, 100 kWh – 2 MWh per unit
  • High-efficiency PCS with 4-quadrant power control
  • Intelligent EMS with peak shaving, TOU, and demand strategies
  • IP54 outdoor rating, -30°C to +55°C operating range
Applications

Designed for Every C&I Scene

From heavy manufacturing to commercial retail, our systems adapt to your load profile, tariff structure, and operational requirements.

01

Manufacturing Plants

High-load factories with shift-based production patterns benefit from peak shaving and demand management, reducing monthly electricity bills by 20–40%.

02

Commercial Buildings

Office towers, shopping malls, and hotels use storage to manage HVAC-driven peak loads and provide backup for elevators, lighting, and critical systems.

03

Industrial Parks

Multi-tenant industrial parks deploy shared or dedicated storage to manage aggregate demand, integrate distributed PV, and improve power quality.

04

EV Charging Stations

Storage buffers fast-charging load spikes, reduces grid upgrade costs, and enables solar-powered charging for fleet and public charging infrastructure.
